Herpes pharyngitis in children is a self-limiting disease caused by enteroviruses (mainly coxsackievirus group A, but occasionally other enteroviruses) and characterized by acute fever and herpes ulcers in the pharynx. The main route of transmission is the fecal-oral or inhalation tract. It is highly infectious, spreads rapidly, is disseminated or epidemic, and has a high incidence in summer and autumn. The general course of the disease is 4-6 days, and in severe cases can be up to 2 weeks. Older children often complain of sore throat, especially when swallowing, and sometimes headache, abdominal pain or myalgia; infants and young children show restlessness, refusal to eat, salivation and vomiting. Most children do not have cough or runny nose. The main signs are in the pharyngeal isthmus, which is initially congested with blood, and a number of scattered herpes of 2-4 mm in size surrounded by a red halo can be seen in the isthmus (pharyngeal arch, soft palate, uvula, etc.), which gradually expands after 2-3 days and breaks down to form a shallow ulcer that can last 4-10 days. Some children may have swollen or painful submandibular lymph nodes, and most routine blood tests are normal or slightly high blood cell counts. Herpes pharyngitis is characterized by herpetic ulcerative mucosal damage, with the main signs manifested in the pharyngeal isthmus. Generally, the tongue, gingiva and buccal mucosa do not show herpes and ulcers, and there is usually no generalized herpes. These features can be distinguished from similar diseases such as herpes stomatitis, ulcerative stomatitis, hand, foot and mouth disease, chickenpox, and pharyngeal conjunctival fever. Since the initial symptoms of herpes pharyngitis are not very different from those of inhalation diseases such as colds or gastrointestinal diseases such as enteritis, it is easy for parents to misidentify the disease and delay treatment. Although herpes pharyngitis is a self-limiting disease, some children have a high early fever, often above 39°C, and may have convulsions; the pain in the pharynx is severe, red and swollen, which seriously affects the child’s feeding; a few can be complicated by bacterial infections or secondary viral myocarditis, which can be life-threatening if complicated by meningitis. Therefore, once a child is found to have high fever and mouth ulcers, it is important to take the child to the hospital in a timely manner. The onset of herpes pharyngitis is multi-causal: 1. own cause – is the weakness of children’s resistance to disease and high susceptibility to enteroviruses; 2. main cause – is due to hot weather, high temperature and high humidity, which is conducive to the breeding and reproduction of enteroviruses (such as coxsackie virus and These pathogenic microorganisms enter the digestive or respiratory tract of children, forming intestinal viral infections, which can also be complicated by bacterial infections; 3, environmental factors – is due to people’s measures to prevent heat and cooling (such as electric fans blowing directly, the use of air conditioning when the temperature is set too low, greedy for cold drinks, etc.) exceed the children’s or weather factors (such as high temperature, wind and rain, sudden temperature changes, etc.) reduce the child’s own ability to resist disease and thus cause the onset of the disease. Treatment is based on oral Chinese medicine, antiviral and symptomatic treatment. Herpes pharyngitis is a damp-heat laryngeal paralysis, mostly caused by external damp-heat attacking the pharynx, and is often treated by detoxifying the throat and reducing dampness and heat. In case of fever, antelope horn powder can be used to clear the fire and reduce fever to prevent frightening wind, and physical therapy can also be used to lower the temperature, and antipyretic drugs such as Torn and Merlin can be used when the body temperature exceeds 38.5℃. If the temperature exceeds 39.5℃, vomiting, convulsions, affecting diet and sleep, the infusion support therapy and symptomatic central cooling measures can be used; if the blood routine check has increased white blood cell count and neutrophils, anti-bacterial drugs can be used. The child should be isolated for 2 weeks, and the food utensils used by the child should be disinfected with boiling water to prevent cross-infection. The same child can be repeatedly infected with the disease because there are various intestinal viruses. During the treatment period, it is necessary to pay attention to rest, do not strenuous activities, sleep enough, drink enough water, eat less, eat more vegetables, do not eat ice-cream, do not drink drinks. The diet should be kept light, drink warm water in moderation, give the child some vitamin-rich vegetables, fruits, etc., and eat as little fried and fried greasy food as possible. Avoid eating irritating food, such as acid, sweet, spicy, salty, hot, hard, etc. Pay special attention not to eat too hot, too cold food, to avoid stimulating the oral ulcers caused by pain. You can take appropriate amount of mung beans, bitter gourd, barley, rice, etc. to cook porridge or soup, and give the affected children to drink in appropriate amount after cooling.
